for ExtendedviewToolkit, there is a webpage [1] and you can download the latest via github [2] [1] extendedview.mur.at [2] https://github.com/extendedview/extended_view_toolkit cheers, Peter Am 09.09.13 23:51, schrieb John Harrison: ExtendedViewToolkit does photo stitching.

glsl is the open gl shader language ... basically a simple C-like language for doing graphics stuff on the GPU, see https://en.wikipedia.org/wiki/GLSL Also, see the OpenGL Orange Book On Sep 9, 2013, at 5:01 PM, pd-list-requ...@iem.at wrote: From: David Schaffer schafferda...@hotmail.com Subject: [PD] GEM noobie: I don't understand this glsl thing... but I need it!

ExtendedViewToolkit does photo stitching.

hello, well, this is a huge subject. there is a lot of documentation on internet. most are a bit technical, but it's a technical subject. cheers c Le 09/09/2013 22:24, David Schaffer a écrit : Hi there, I'm in the process of writing my own photo stitching/assembling abstraction but I'm having a lot of trouble understanding what the glsl object do...
